To jailbreak a ps3 you have to downgrade your ps3 to 3.55 then install a 3.55 cfw then you can choose the cfw you want to go on then you will be able to install mods for gta 5 and other games then go online

How do I downgrade it? And install those

If it's even downgradeable, you use hardware such as an e3 flasher. Cost around $100.

Like christian said you need to make sure the ps3 is compatible to downgrade if it is you then need to downgrade it using a E3 flasher that cost around 100$ or you can pay someone to do it for you for around 60-80$
